To study the difference between two internal fixation methods Kaneda and Z-plate in the operation of anterior surgical approach and decompression after thoracolumbar fractures.
The bio-mechanical structure of the internal fixture, install when operating, complications and time of the operation were compared in the cases by Kaneda and Z-plate.
Z-plate method had the following characteristics: reasonable of the bio-mechanical structure; stability after internal fixture being installed; capability of completely propping up the injured centrum and keeping the height of middle-column; simple operation when installing internal fixture and shorter time of operation (1.1 hours, P < 0.05); fewer complications.
Z-plate is an ideal internal fixation method in the operation of anterior surgical approach after thoracolumbar fractures.
研究胸腰椎骨折前路手术减压中两种内固定方法（Kaneda和Z-plate）的差异。
对采用Kaneda和Z-plate的病例，比较内固定生物力学结构、术中安装情况、并发症及手术时间。
Z-plate方法具有以下特点：生物力学结构合理；内固定安装后稳定性好；能完全支撑损伤椎体并保持中柱高度；内固定安装操作简单，手术时间短（1.1小时，P<0.05）；并发症少。
Z-plate是胸腰椎骨折前路手术后理想的内固定方法。
